Great suggestions so far guys, keep em coming!
Here's some I loved!:
* New content added should be on the existing continents and not lots of new zones
* Implement planar access in a similiar fashion to Hate, Fear and Sky
* Do not make Velious end game content obsolete
* Create custom AAs and implement them in a different way
* Add more Player-to-Player Orientated content, PVP, Coop etc
* Do not make the game easy
* Do not change our current trading system (East Commonlands)
* Bring back some of the favourite luclin zones (Bring Ssra back to Norrath? Overthere maybe?)
* More dragons
* If races from other expansions are added keep them old world (Kerra Ridge was one idea)
* Never trivialise travel (Pok Books, Nexus etc)
* Playable Monsters - See
Project M
* Implement Dirty High Elf Women
